find your own game and stick with that.if it was a putt then putt straight at the chains,if an approach shot just from outside your putting distance,then a hyzer shot with a roc would work,works for me outside my putting distance.
I tend to use a hyzer putt with a tail or head wind. To cut down on the wind messing with it. Mind you I still throw it dead straight (no true fade on the putt). This was taught to me by a local pro and it has worked well for me, but on non windy days I throw as flat as possible. However, I've never heard of putting with a constant hyzer angle. Does not mean it's not true, I've just never heard that.
I've heard different arguments. Some say you shouldn't hyzer putt because you lessen the surface area of the disc that is striking chains. So I wouldn't go too extreme with the angle.
That said, I've watched a putting clip with Climo where he talks about putting with hyzer. He says for him it elimates the left or right misses. He also plays the wind with it.
I tend to go flat as much as I can... and I find the wind messes with it less in crosswinds so that's what I practice most. The times I've tried hyzer putting in practice I have found that I seem to get a really clean release. Almost like that's the body's natural inclination when you use the putting motion. So I go back and forth some. I also vary my putting style based on the landing angle to mitigate rollaways if I miss.
i would say the reason some people putt with hyzer angle on their putts is predictability. similar to the way an overstable disc will finish left, a hyzer angled putt will do the same (RHBH). not saying that one is easier to make it in the chains, just referring to the fact a hyzer angled putt is predictable.
